In Part 1 of this electric guitar video lesson, brought to you by GuitarJamz, host Marty Schwarz will teach you how to play "Sir Duke" by Stevie Wonder. As you follow along with him, he teaches you the intro of the song, breaking it down slowly so that you can follow along with him. Then he moves on to the progression of the chords used in the song, breaking down each part of the song, teaching you the chords and explaining the strum pattern and picking of the guitar riffs. You will learn the B major barre, G# minor, G major 7, Gb7, F7, E9, B major, F minor 7, E major 7, C# minor 7, and F#9 chords, which are also illustrated in a tablature type notation on screen as he plays.
